Mine are raty, rusty, and just plain awful. I was wondering if anyone has had any trouble with these replacement floats? Seems like a straight forward part that should just line right up and work (assuming I adjust its height correctly). Any thoughts?

It'll work, but please only use the book float height as a starting point.
Check your work with the clear tube test, to make sure the bowl fuel level is correct.
Correct fuel level is the goal.  Actual float height measurement is irrelevant.

That's the plan, thanks! Supposing I adjust my height correctly. Could I perform a clear tube test on my bench? Does it matter that the fuel supply would be coming from a bottle suspended above the carb?

Just suspend the bottle of fuel, run the fuel line into the carb, have the clear tube set up, and see where the level rises to. Mark/measure, and repeat for the other three. Unless I'm missing something.

Yes.  On the bench is the most efficient way to do it...IMO.

That's kind of what I figured. I'm a ways away from that. I'm just disassembling the carbs while I wait to paint my engine. Once that's painted, reassembling the engine is priority, then I will come back to carbs when its time. I have a hard time sitting idly by while I could be getting parts at least kind of ready for rebuilding.
